摘要： A burner block (12) for mounting a burner (14) within a furnace containing a melt to be heated by the burner. The burner block comprises a body (20) having a passageway (22) terminating in a divergent opening (24). The passageway is configured to receive the burner so that the burner is recessed within the divergent opening (24) and a flame (16) produced by the burner is directed out of the divergent opening and over the melt (18). The divergent opening has a lower section (26) angled in a downward direction and the lower section has a reversed step (28) to produce a primary recirculation zone (A) beneath the flame, thereby to draw the flame in a downward direction toward the melt. The reversed step is positioned within the divergent opening so that when the burner is in use, a secondary recirculation zone (B) forms between the opening and the melt and further draws the flame in the downward direction toward the melt. The height of this secondary recirculation zone will vary with the height of the melt within the furnace to produce a self adjustment of the flame toward the melt. In another aspect, the present invention relates to a furnace incorporating the aforesaid burner block, a burner positioned within the burner block and a melt.
摘要翻译：一种用于将燃烧器（14）安装在含有待由燃烧器加热的熔体的炉内的燃烧器块（12）。燃烧器块包括具有终止于发散开口（24）的通道（22）的主体（20）。通道构造成容纳燃烧器，使得燃烧器在发散开口（24）内凹入，并且由燃烧器产生的火焰（16）从歧管开口并在熔体（18）上方引出。发散开口具有向下方向成角度的下部部分（26），并且下部部分具有相反的台阶（28）以在火焰下面产生主要再循环区域（A），由此沿着向下方向熔化。相反的台阶位于发散开口内，使得当使用燃烧器时，在开口与熔体之间形成第二再循环区域（B），并进一步将火焰向下引向熔体。该第二回流区的高度将随着炉内熔体的高度而变化，以产生火焰朝向熔体的自我调节。另一方面，本发明涉及装有上述燃烧器组件的炉子，位于燃烧器组件内的燃烧器和熔体。

摘要： The components of a gas mixture are separated by pressure swing adsorption in a plurality of adsorption vessels. In the first step of the half-cycle adsorption takes place in a first bed while the second bed undergoes countercurrent desorption. At the end of the first step the first bed is vented countercurrently and the first and second beds undergo, as a first bed equalisation step, outlet-to-outlet equalisation or outlet to both inlet and outlet equalisation. The vent step may precede or be concurrent with the first bed equalisation step. In a second equalisation step the beds simultaneously undergo inlet-to-inlet and outlet-to-outlet equalisation. The second bed is then further pressurised with nonadsorbed product gas. The half cycle is then repeated but with the first bed being substituted for the second bed and vice versa.

摘要： A stream of compressed air is cooled in a heat exchanger 20 to a temperature suitable for its separation by rectification. The compressed air stream is separated by rectification in an air separation unit 22. A pressurised nitrogen stream is withdrawn from the unit 22, is cooled in the heat exchange 20, and is expanded in a turboexpander 30 with the performance of work. The expanded stream is drawn through the heat exchanger 20 from its cold end to its warm end by a blower 34 which has an inlet pressure below atmospheric pressure. The blower 34 raises the pressure of the expanded stream to at least atmospheric pressure.

摘要： A hydrocarbon cracking catalyst having coke deposits thereon is regenerated by the combustion of the deposits in a regenerator 2 having a lower combustion zone 12 and an upper reducing zone 14. A mixture of oxygen and an inert gas (e.g. nitrogen or carbon dioxide) is introduced into the combustion zone 12 through a distributor 18. The combustion zone 12 is at least 24% by volume of the total flow rate of all gases into the zone 12. At least part of the coke is combusted. In addition nitrogen in the coke is converted to nitrogen oxides (NO x ). A substantially oxygen-free combustion gas comprising carbon dioxide, nitrogen oxides and at least 1% by volume of carbon monoxide flows into the reducing zone 14 with the result that at least part of the nitrogen oxides are reduced to nitrogen.

摘要： A hydrocarbon feedstock is cracked in reactor 2. Used catalyst is sent to a regenerator 4 in which coke deposits on the catalysed are oxidised in the presence of the gas mixture comprising oxygen and inert gas (e.g. CO₂). Regenerated catalyst is returned to the reactor 2. A cracked hydrocarbon product stream flows to a fractionating column 6. An overhead stream from the fractionating column 6 is cooled so as to form a liquid-vapour mixture. Downstream of phase separation in an accumulator 10, a stream of the vapour phase ("wet gas") has methane and hydrogen separated therefrom by pressure swing adsorption in plant 8. Higher hydrocarbons than methane are adsorbed in the plant 8 and on regeneration of the adsorbent form a desorbed gas fraction which is sent to an upstream wet gas compressor 12 and from there to a downstream wet gas compressor 16. A compressed wet gas stream is sent from the downstream wet gas compressor 16 to further hydrocarbon processing units (not shown). The feed to the PSA plant 8 may be taken from upstream of the compressor 12 or from intermediate the compressors 12 and 16, or from both locations. Throughput of hydrocarbon feedstock through the cracking plant is able to increased.

摘要： A mechanism used in connection with determining a time resolved interaction between a target substance, for instance, an adsorbent and at least one agent, for instance, an adsorbate capable of interacting with the target substance. In accordance with the method the target substance and agent(s) are introduced into a sample vessel. At the same time, the target substance is oscillated within the sample vessel without changing the volume of the sample vessel. A concentration of one or more components associated with the time resolved interaction as a function of time is measured by measuring chamber pressure and simultaneously performing a mass spectroscopical analysis of chamber content at discrete time intervals. The target substance is oscillated by a mechanical movement which oscillates a sample holder configured to hold the target substance. The movement has a finger-like member, preferably formed by welded steel bellows and a curved member rotating within the finger-like member so that motion of the finger-like member does not change chamber volume and therefore effect the pressure measurements that are to be made in accordance with the method.
